I am sorry you got the above response and I/no one else saw this any sooner to respond in a more appropriate, empathetic manner fitting your circumstances. Of course you are scared and shocked and any other manner of emotion right now. <img src="i/expressions/rose.gif" border="0"> None of us will ever forget the day our child was dx'ed, no matter how old they were.
First, I am SO glad that to date your son is doing well. <img src="i/expressions/face-icon-small-smile.gif" border="0"> The time around diagnosis is always so overwhelming... whether they are babies or older. My daughter was 7 when she was diagnosed. Many here have had children diagnosed around the same age as your child.
What to expect at your first clinic appointment: it will no doubt feel kind of overwhelming- there are a lot of people you will meet there who you'll see at each visit; so expect to be there for a good couple hours. There is a nutritionist who will be advising you on how best to help your baby grow/gain weight as he gets older. A social worker is instrumental through this early time in helping work out insurance issues and in helping your family learn about the disease and make sure all of you are getting through this time ok. The respiratory therapist will teach you how to do chest physical therapy on your baby to help keep airways clear (once he's older the rt will assess lung function at visits.) The cf nurse is someone you will get to know- you see this person at each visit and likely speak to them when you call the clinic when your child is sick. You will also, of course, meet at least one of the pulmonologists there who specializes in cf. The baby may have labs drawn as a baseline (they like to check vitamin levels and other routine stuff yearly), maybe a chest xray, also to get his baseline and a sputum sample will be taken (back of throat will be swabbed in all likelihood.)
My daughter has one df508 mutation, we aren't sure of her other one. Maybe someone else will come along who knows about the other one your child has. However, in the world of cf, no 2 cases are the same- you can have two people with identical mutations (even within the same family) and they can turn out very differently. So doing the best you can to learn about the disease and to be proactive with treatment to stay ahead of things is the most valuable thing you can do. There is a lot of support to be had here... come to the Families forum to meet other parents. <img src="i/expressions/face-icon-small-smile.gif" border="0">
